We pretty much agree. They don't compare him to Mahomes because it's clearly ridiculous. However, many people have compared him to Brady, which is probably more absurd.1. I don't think anyone is putting Purdy in the same category as Mahomes, etc.
2. Him having to face adversity hasn't been his fault. He's playing with the best defense since the Hawk's D of 2012-2013. So it's not like he's needed to make a bunch of 4th quarter comebacks.
He's running Shanahan's offense to perfection with an insane supporting cast. That's been impressive, as much as it hurts me to say it.
My point with that analogy was highlighting the insignificance of stats/wins when evaluating QB skill. For example, statistically, Purdy is significantly better than Mahomes (and the others mentioned) this season. And if the argument is that he's not a product of Shanahan's system/talent, then we'd have to assume he's close to that elite level. I don't think he's anywhere near it.
